What you're sourcing
The 3VA1132-5ED42-0AA0-ZD00 is a Siemens 3VA1 IEC frame 160 molded-case circuit breaker, 4-pole, rated 32 A with a TM210 thermal-magnetic trip unit. It carries a 55 kA Icu at 415 V — breaking capacity class M — meaning it can interrupt a fault current up to 55 kA at that voltage without damage, which is the figure you need for panel SCCR coordination. This variant is configured for line protection (FTFM) with fixed short-circuit protection set at 10 × In and fixed overload protection Ir = 32 A. The N conductor is unprotected, and it ships with a nut keeper kit — the suffix ZD00 flags it as a DC Power OEM part built for the China market.
Deployment context
Mounts in a standard DIN-rail enclosure or panel-mount footprint typical of IEC-frame MCCBs. The nut keeper kit simplifies installation in OEM builds where fasteners are pre-assembled.
